There is, Squidge, but you'll have to edit the registry. If you feel comfortable doing that, then backup first and navigate, using the little + signs to:
Clicl on that "TypedURLs" folder and it's contents will open in the right-hand pane. Right click on the URL of the hotels in that pane and choose delete. Exit the registry, re-boot your computer and those URLs should be gone.
You can delete *all* the URLs easier than that, but that would give the game away. ;-)
PS Have a nice time away.
